Abstract
This device includes an acquired data storing unit for storing acquired data about a current command value of a servo motor configuring a robot drive system; a tendency diagnosis unit for diagnosing a future changing tendency of the current command value based on the data of the current command value stored in the acquired data storing unit; and a life determining unit for determining a term until the current command value reaches a previously set value based on the future changing tendency of the current command value acquired by the tendency diagnosis unit. Thus, a residual life of the robot drive system can be accurately predicted.
Claims17
A robot maintenance assist device for predicting a life of a drive system of a robot so as to assist a maintenance, comprising:
- an acquired data storing unit for storing an acquired data about a current command value of a servo motor configuring the drive system of the robot;
- a tendency diagnosis unit for diagnosing a future changing tendency of the current command value based on the data of the current command value stored in the acquired data storing unit;
- and
- a life determining unit for determining a term until the current command value reaches a previously set value based on the future changing tendency of the current command value acquired by the tendency diagnosis unit.
